1 - 22 . (canceled)
23 . A ball component of a ball-and-socket prosthesis comprising a head and a stem, wherein the stem comprises one or more truss structures, each of the truss structures comprising two or more struts joined at a node, wherein the one or more truss structures are configured to interface with bone tissue.
24 . A ball-and socket prosthesis comprising:
a cup; and
a ball component comprising a spherical head and a stem, wherein the stem comprises one or more truss structures, each of the truss structures comprising two or more struts joined at a node, wherein the one or more truss structures are configured to interface with bone tissue.
25 . A method, comprising:
coupling a ball component to a bone, wherein the ball component comprises a spherical head and a stem, wherein the stem comprises one or more truss structures, each of the truss structures comprising two or more struts joined at a node, wherein the one or more truss structures are configured to interface with bone tissue;
coupling a cup to the bone of a subject; and
coupling the ball component to the cup.
26 . The ball component of claim 23 , wherein the truss structures comprise two or more struts coming together at a node to form a point.
27 . The ball component of claim 23 , wherein the struts of the truss structure define an opening in the truss structure that allows bone material to pass through the truss structure.
28 . The ball component of claim 23 , further comprising one or more bone screws coupled to head.
29 . The ball component of claim 28 , wherein the bone screws and truss structures extend in the same direction, substantially parallel to each other, from the head.
30 . The ball-and socket prosthesis of claim 24 , wherein the truss structures comprise two or more struts coming together at a node to form a point.
31 . The ball-and socket prosthesis of claim 24 , wherein the struts of the truss structure define an opening in the truss structure that allows bone material to pass through the truss structure.
32 . The ball-and socket prosthesis of claim 24 , wherein the ball component further comprising one or more bone screws coupled to head.
33 . The ball-and socket prosthesis of claim 32 , wherein the bone screws and truss structures extend in the same direction, substantially parallel to each other, from the head.
34 . The method of claim 25 , wherein the truss structures comprise two or more struts coming together at a node to form a point.
35 . The method of claim 25 , wherein the struts of the truss structure define an opening in the truss structure that allows bone material to pass through the truss structure.
36 . The method of claim 25 , wherein the ball component further comprising one or more bone screws coupled to head.
37 . The method of claim 36 , wherein the bone screws and truss structures extend in the same direction, substantially parallel to each other, from the head.
